MPL error when using planar images in GCC 4.4

[Robert Fendt <rmfendt@…>]

Trying to create an instance of e.g. rgb8_planar_image_t when using GCC 4.4, the following template error is produced:

error: ‘template<class Sequence, long int N> struct boost::mpl::at_c’ is not a function

The test code is very minimal, just trying to create an object of type rgb8_planar_image_t; the problem actually occurs with all planar types.

Reproduced in Boost 1.38, 1.40 and 1.41beta1; GCC version is 4.4.1-4ubuntu8 on Kubuntu 'Karmic'.

Test case

Note: the problem does not seem to occur when using GCC 4.3, though I have not tested that thoroughly, yet.

I think this might be a dup of #3041 (fixed on Trunk, but not yet merged to release).

I think you are right. In any case I can confirm that the problem seems to be non-existent in current SVN trunk (2009-11-14). Thanks for the hint.

(In [58777]) Added gil:: namespace to all at_c calls. This seems necessary for current gcc ( 4.4 and more ) compilers. See #3041 and #3619.

I have tried to reproduce the problem with the current trunk ( 01/06/10 ) and release branch using MinGW 5.1.6 ( gcc 4.4 ). The problem could not be reproduced.
